Welcome back to the Bluewell Peptides Weekly Roundup, your trusted update for research insights, peptide industry developments, and regulatory news.
This week, we cover the recent MHRA enforcement update regarding unlicensed injectable products, highlight the continued growth of multi-peptide blends such as Glow and Klow, explore key growth-hormone research compounds, and review the rising interest in MOTS-c and 5-Amino-1MQ. We also provide an important update on international delivery times and customs processes ahead of the busy winter period.
MHRA Investigation and Bluewell Peptides Compliance
A recent MHRA investigation exposed an operation distributing unlicensed injectable weight-loss medicines, including products falsely labeled as retatrutide. These items were filled into preloaded pens and sold for human use, which is illegal under UK medicines regulations.
At Bluewell Peptides, we fully support the MHRA’s enforcement actions. Our company does not sell, promote, or condone any form of human use. All products are supplied strictly as research-grade materials in lyophilised (freeze-dried) powder form.
We provide full documentation, batch traceability, and independent HPLC purity verification for every compound. Our protocols include:
- Research use only labelling on all products
- Lyophilised powder format only, never prefilled or liquid forms
- No sale of injection equipment or pens
- Full COA and batch documentation supplied
- Strict compliance and checkout terms confirming non-human use
Our Retatrutide is provided exclusively in lyophilised (freeze-dried) powder form, accompanied by full COA documentation and independent HPLC purity data (≥99.1%). Each batch undergoes verification to confirm authenticity and purity prior to dispatch.
Bluewell Peptides operates transparently, in full compliance with UK and EU regulations. We support the MHRA’s mission to protect public safety and maintain the integrity of the legitimate research supply chain.

Glow and Klow Blends Growing in Popularity
Among researchers, Glow Blend and Klow Blend continue to attract attention for their multi-compound formulations. These blends combine well-established research peptides such as BPC-157, TB-500, GHK-Cu, and KPV within a single vial, designed to simplify research procedures and improve consistency across trials.
Each peptide within these blends is studied for specific roles in cell migration, repair, and recovery pathways. Researchers often prefer the convenience of a single pre-formulated vial for comparative and time-sensitive analysis, while others choose individual peptides for precision testing.
Glow and Klow represent the ongoing shift toward integrated peptide formulations that enhance workflow efficiency and reproducibility in controlled research settings.

KPV Peptide Research Overview
KPV (Lysine–Proline–Valine) is a naturally occurring tripeptide derived from the C-terminal region of alpha-melanocyte-stimulating hormone (α-MSH). It is increasingly studied for its potential role in inflammation control, epithelial integrity, and immune system modulation.
In research environments, KPV has shown the ability to interact with inflammatory signaling pathways such as NF-κB and cytokine cascades. These effects make it a valuable compound for ongoing investigations into barrier protection, oxidative stress, and wound recovery models.
Researchers frequently include KPV in studies alongside BPC-157, GHK-Cu, and TB-500, forming part of a broader class of peptides associated with regenerative and anti-inflammatory research.
Due to its small size, high stability, and clean safety profile in controlled experiments, KPV remains a reliable candidate for extended testing in laboratory environments focused on tissue health, recovery, and immune response.
Interest in KPV research has grown steadily throughout 2025, highlighting its position as one of the key supporting compounds in modern peptide science.
Semorelin, Ipamorelin, Tesamorelin, and CJC-1295
Research interest continues to expand around growth hormone-releasing peptides including Semorelin, Ipamorelin, Tesamorelin, and CJC-1295. These compounds are studied for their role in stimulating the body’s natural pulsatile growth hormone secretion cycle.
Each peptide offers distinct characteristics for targeted research applications:
- Sermorelin: A synthetic analog of growth hormone-releasing hormone (GHRH 1–29) and is commonly used in research focused on the growth hormone (GH) axis. It plays a key role in stimulating the anterior pituitary to release endogenous GH, making it a valuable tool for studying pituitary function and age-related declines in GH production.
- Ipamorelin: A selective growth hormone secretagogue that targets the ghrelin receptor. It is highly regarded in laboratory settings for its clean GH-releasing profile, as it stimulates GH without significantly affecting other hormones like cortisol or prolactin. Its precision and low side effect profile make it a popular choice in GH optimization research.
- Tesamorelin: A stabilized analog of GHRH developed for enhanced metabolic stability and a longer half-life. It is widely studied for its potential to improve body composition, particularly in reducing visceral fat and enhancing insulin sensitivity. Its effects on metabolic regulation continue to be a focus of ongoing research.
- CJC-1295: A long-acting analog of growth hormone-releasing hormone (GHRH), designed to stimulate sustained elevations in growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels. There are two versions commonly referenced in research:
CJC-1295 with DAC, this version includes a Drug Affinity Complex (DAC), allowing it to bind to albumin in the bloodstream. This significantly extends its half-life — up to 6–8 days — enabling less frequent dosing in research environments while maintaining consistent GH stimulation.
CJC-1295 without DAC (often called Mod GRF 1-29): This is a short-acting version that more
closely mimics the body’s natural pulsatile GH secretion. Its half-life is approximately 30 minutes, which allows for quick clearance and makes it useful in studies focused on replicating natural GH release patterns.
These peptides represent some of the most frequently studied GHRH analogues in modern endocrine and metabolic research.
5-Amino-1MQ and the NAD+ Pathway
5-Amino-1MQ and the NAD⁺ Pathway
Recent studies on 5-Amino-1MQ (5-Amino-1-methylquinoline) have drawn increasing interest in the research community due to its role in energy metabolism and NAD⁺ biosynthesis. This compound is being studied for its ability to inhibit nicotinamide N-methyltransferase (NNMT) — an enzyme known to regulate levels of NAD⁺ precursors such as nicotinamide (NAM).
By inhibiting NNMT, 5-Amino-1MQ may help preserve cellular pools of NAM, potentially leading to increased NAD⁺ availability, which is essential for mitochondrial function, sirtuin activation, and overall metabolic activity.
In preclinical models, administration of 5-Amino-1MQ has been associated with improvements in muscle strength, endurance, and energy expenditure, particularly in aged or metabolically compromised subjects. Some studies suggest that these effects may surpass those achieved by exercise alone in similar models, though further investigation is needed.
Researchers continue to explore 5-Amino-1MQ’s connection to NAD⁺ metabolism, mitochondrial performance, and skeletal muscle physiology, as interest grows in compounds that may influence metabolic health and cellular resilience.
MOTS-c and the Mitochondrial Research Frontier
MOTS-c is a mitochondrial-derived peptide that acts as a systemic regulator of metabolic homeostasis. It has been the subject of increasing research due to its potential role in glucose regulation, insulin sensitivity, and muscle energy management.
Produced naturally by the mitochondria, MOTS-c plays a part in cellular adaptation to metabolic stress and may contribute to improved energy balance, bone metabolism, and fat cell activity.
Researchers studying mitochondrial peptides are particularly focused on MOTS-c’s ability to influence skeletal muscle metabolism and promote healthy aging mechanisms.
MOTS-c’s unique origin in mitochondrial DNA places it at the forefront of metabolic and longevity research, marking a growing area of focus for 2026.
